London, Nov 14 - Pop singer Christina Aguilera has admitted that she is nocturnal and prefers working late at night.

"When the sun goes down, my whole body starts to come alive, although I am a little different now because I do have a child and my hours have been turned upside down for him," contactmusic. com quoted Aguilera as saying.

"But I am still naturally a night owl. I love to work between 3-4 a. m." she added.

These days Aguilera finds it difficult to follow this regime, thanks to her 21-month-old son Max.

"Now I am a mother. I am getting up early. It is 6 a. m. every day and even though I am a night owl, now I have to go to bed by 12.30 a. m. All thanks to my son, who has forced me to change my sleeping pattern," explained Aguilera. (IANS)
